Utilization of Distillery Wastewater for Electricity Generation Using Microbial Fuel Cell

Anand Parkash

Abstract


Energy crises is a serious problem all over the world; there is a need to identify new technologies and renewable resources to fulfill this energy requirements. Due to the increase in awareness environmental problems, that biofuels production is eco-friendly. Ethanol is one of the future fuel that is produced from sugar cane molasses. During distillation of alcohol wastewater also called draw off, this wastewater contains many organic matters, that organic matter can be utilized for power generation. Microbial fuel cell (MFC) is one of the major source of treating wastewater and for electricity generation. This research explores the application of double chamber MFC in generating electricity using distillery wastewater. The different concentration of wastewater has been performed. The maximum current, voltage, BOD, COD, pH and TDS obtained with respect to time. MFC of distillery wastewater showed removal efficiency 69.3% COD, 68.1% BOD and 56.35% TDS with different feed concentration. The current, voltage and power generation in the reactor is 1.28 mA, 0.9 V and 0.304 W/m2 respectively. This study also deals about the factors like length and concentration of salts in salt bridge that affecting on MFC’s efficiency.
